BATTERY-TERMINAL REMOVER.

To all whom it may concern:

Be it known that I, HIRAM Vi. Sarrnns, a citizen of the United States,residing at Aberdeen, in the county of of South Dakota, have inventednew and useful Improvements in Battery-'lerminal Removers, of which isfollowing is a specification.

This invention relates to improvements in terminal removers for storagebatteries and the like and has particular application to a device forremoving conductor terminals from binding posts of the type used on theW'illard storage battery.

As is well known, the conductor terminals in the binding posts corrodemore or less and have a tendency to stick in the binding posts and theusual method of removing the terminals of the conductors from thebinding posts is to loosen the set screw and drive the terminals out ofthe binding post by means of a hammer or similar tool. lhis method ofremoving the conductor terminals from the binding posts results in themuti lation of the terminals as well as the binding posts and itfrequently happens that the rubber casing of the battery is broken orfractured and the plates loosened in the battery, thereby shortening thelife of the battery and doing other injury thereto.

In carrying out the present invention, it is my purpose to provide aterminal remover for storage batteries whereby the terminals may beforced out of the binding posts under pressure without the use of ahammer or,similar tool and whereby the terminal will be removed from thebinding post gradually and without shock or jar to the battery, therebyeliminating the mutilation of the binding post andterminal andpreventing cracking of the battery case and loosening of the plates.

It is also my purpose to provide a terminal remover of the classdescribed which may be applied to the storage battery quickly andconveniently and which may be operated readily and with a minimum cliorton the part of the operator, thereby enabling the terminal to be removedfrom the binding post with ease and facility.

Another object of my invention is vide a storage battery terminal whichwill embrace the desired features of durability, which simplicity,eliiciency and kit, or about the may be carried in a tool Brown andState person and wherein the component parts will be so arranged andcorrelated as to reduce the possibility of derangement to a minimum andenable such parts to be repaired or replaced whenever necessary.

With the above and other objects in view, the invention consists in theconstruction, combination and arrangement of parts here inafter setforth in and falling within the scope of the claims.

In the accompanying drawings:

Figure 1 is a view in elevation of a battery terminal removerconstructed in accordance with the present invention, the same beingshown in use.

Fig. 2 is an edge view of the terminal remover.

Fig. 3 is a top plan view thereof.

Fig. l is a vertical sectionalview therethrough.

Fig. 5 is a horizontal sectional view on the line 5-5 of Fig. 1.

Fig. (i is a similar view on the line 6-6 of Fig. 1.

Fig. 7 is an enlarged fragmentary vertical sectional view on the line 77of Fig. 1.

Referring now to the drawings in detail, 1 designates a storage battery,while 2 indicates the binding posts connected to the terminal posts ofthe plates of the storage battery. In the present instance, each bindingpost 2 comprises a block 3 formed with a transverse opening 4 graduallydecriasing in diameter from one end toward the other. 5 indicates theterminals of the conductors and those terminals are shaped after thefashion of the openings 4 in the resprrtive blocks 3 and each has theend thereof formed with a threaded bore 6 in which is threaded a setscrew or clamping screw 7. After the terminals 5 are passed into theopenings l in the blocks 3, the set screws 7 are thrrndcd into the bores6 and the heads of the screws bear against the adjacent edges of theblot-ks to draw the terminals into the openings so as to form a goodelectrical connection between the binding posts and the terminalswhereby the current from the battery may flow through the conductors Myimproved terminal remover is indicated as an entirety by the ninneral 8and, in the present instance, comprises legs 9, 9 spaced apart inparallelism and having the extremities flu-roof atone end of the deviceformed with a yoke 10 and block ll respecllll votally tively adapted toengage one edge: of the block 3 of the binding post and the outer end ofthe set screw, the yoke 10 surrounding the terminal 5, clearlyillustrated in Fig. 1 of the drawings. 12 designates a longitudinallycurved bar having the inner edge thereof formed with grooves 13 adjacent to the respective ends of the bar and formed on the side walls ofeach groove 13 are beads 14:. This bar 12 is mounted upon the other endsof the legs 9 and the ends of the legs are disposed within the grooves13 respectively and the opposite sides of each leg are formed withgrooves 15 that receive the beads 14 so as to hold the bar 12 againstaccidental removal from the legs and permit sliding of the ends of thelegs within the grooves 13. Formed in the bar 12 centrally thereof is anopening and mounted within the opening is a bushing 16. Threaded throughthe bushin r 16 is a screw shaft 17 arran ed between the legs 9 andhaving one end t ereof terminating short of the firstmentioned ends ofthe legs and the other end terminating ad acent to the outer edge of thebar 12. The threads on the shaft 17 extend from the last-mentioned endthereof to a point approximately centrally of the length of the shaftand formed in the shaft 17 adjacent to the center thereof and to thefirst-mentioned end are grooves 18, 18 respectively and surrounding thegrooved portions 'of-the shaft are collars 19 each ormed, atdiametrically opposite points, with outwardly projecting pivot cars 20.Pivoted within the cars 20 on the collars are the inner ends of links 21respectively and the outer ends of the links 21 are pivconnected to theadjacent portions of the legs 9. The links 21 adjacent to the bar 12 arerelatively long and normally diverge upwardly and outwardly from eachother, while the other links 21 are normally arranged horizontall Formedon the outer end of the shaft 1 is an angular head 22 having the inneredge formed with an outwardly projecting shoulder 23. 24: designates asocket member adapted to fit over the head 22 and shaped to conform tothe configuratioirof the head and pivoted upon the outer end of thesocket member 24 is a handle 25, while formed integral with the socketmember is a ratchet disk 26. livoted upon the handle 25 is a doubleended pawl 27 having the ends thereof capable of interchangeableengagement with the ratchet disk 26 so that the disk, the socketmembeiaand the shaft 17 may be rotated in one direction or the other.Secured to the *llltl' edge of the bar 12 and projecting outwardlytherefrom are pairs of pins 28 disposed at opposite sides of the shaft17 respectively. 29 designates a handle formed, :uljacent to one end,with openings 30 adapted to receive the pins of either pair 28 andcapable of interchnngeablc association with such pins so that the devicemay be held against bodily turning movement in the rotation of the shaft17 under the action of the handle 25 and pawl and ratchet mechanism.

In. practice, the yoke end 10 of the leg 9 is placed over the terminal 5and engaged with the block 3 of the binding post, while the block 11 onthe other leg 9 is engaged with the head end of the set screw 7 afterthe latter has been loosened. The device is held in place by the handle29 and the shaft 17 rotated under the action of the pawl and ratchetmechanism and the handle 25. In the rotation of the shaft 17, such shaftis drawn upwardly with the effect to spread the upper links 21 and drawthe lower links 21 toward each other, thereby swinging the binding postends of the legs 9 together and spreading the other ends of such legs,the last-n'ientioned ends of the legs riding in the grooves 13 in theinner edge of the bar 12. In this swinging of the arms 9, a, pressure isexerted upon the set screw 7 and the terminal 5 with the effect to forcethe terminal out of the opening 4 in the block 3 of the binding post.

It will be seen that the terminal isthus quickly and easily detachedfrom the binding post without the use of a hammer or other instrument,while practically no strain is placed upon the casing of the storagebattery or upon the plates.

While 1 have herein shown and described one preferred form of myinvention by way of illustration, I wish it to be understood that I donot limit or confine myself to the precise details of constructionherein described and delineated, as modification and variation may bemade within the scope of the claims without departing from the spirit ofthe invention.
